` Application tiled December 26, 1883. Renewed May 8, 18 85. Serial No.164,836. (No model.)

Toull whom it may concern.-

Be it :known that I, OMAR H. JEWELL, a citizen of the United States ofAmerica, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inLubricators, of

which `the following'is a specification, reference' i being had thereinto the accompanying drawings. l

My invention relates to lubricators, and has for its object theconstruction of a simple and eeetive oil-cup.

To that end it1consists of the novel devices and combination of devices,as will be described and claimed.

Reference will be made to the accompanying drawings, in which Figure 1is a vertical see-m ltional vle'w of the cup,`and Fig.an elevationshowing the cup in position for use.

Like letters refer to like parts in each View.

A representsthe base of the cup provided with means for attaching it ina suitable position, and upon its upper edge `with anupwardly-projecting fiange, a.

B represents the top of the oil-cup, which is provided withdownwardly-projecting flange b, between-which and flange a the glasstube C is situated, said tube forming the wall of the cup. v

Pivoted to one side of base A is a bell-crank` lever, c, so situatedthat one of its arms will be operated upon by the crossbar D when saidbar is reeiproeated, while its other arm occupies a position :directlybeneath a rod, E, which, after passing th rough suitable bearingssecured to or forming part of the cup, is secured at its upper end to ayoke, F.

Passed' around rod E is a spring, G, which is situated between the upperbearing of `said rod and an adjustable collar, H, mounted thereon, theadjustability of which renders it possible to vary the tension to be`applied to rod E to make the return-stroke, as will be described.

To the opposite end of yoke F is secured the plunger-rod I, whichpassesthrough an opening in the top plate, B, and is detachablysecuredat its lower end to a screw-threaded block, d. Below thescrew-thread ofblock d is a downthe plunger has thus been carried back, the

wardly-projecting pin, e, the use of which will be explained.v

J represents the plunger-head, which is hollowed out to form a chamber,f, as shown, said chamber extending from a point near the bottom of saidheadito the topthereof, and communicating at its lower end with a port,g, also made in said head and which is closed by an upwardly-openingvalve, l1.` At or about its center plunger-head J is provided on itsouter face with a circumferential groove, e', communication between saidgroove and chamber f being established through openings j provided forthat purpose. The raised portion which forms the seat for plunger J, andwhich 'is cored out to accommodate it, is provided with passages 'k Z,the one k communieating withthe interior of the cup, while the one l isclosed at its endibyaplugi as shown.

Passage Z communicates with a passage, m, which is' closed by a Valve,n, and which in turn communicates with a pipe, K, which is passedthrough the top plate of the cup, and by suitable couplings is carriedto the steamchest L, as in Fig; 2. The` passages k Zy open into thespace formed forplunger J. 7 5

A screw-stem, M, is passed throughthe side of the base-plate A, andoccupies a position directly opposite the opening of passage 7c',whereby the ilow of the oilis regulated.

By providing the block d with the downwardly-projecting pin e, theopening of the valve h can be regulated;

The operation is as follows: The cup is Ii'lled with oil and theregulatingscrew M is adj usted to admit to passage k the desired amountof oil. The cross-head then contacting with the arm of bell-crank leverc, forces up the rod E andwith it the plunger I J. As the plunger isthus raised, a vacuum is created below it and oil is drawn in throughpassage k. The cross-head then being withdrawn, the spring G carries rodE and the plunger back, and the valve h is opened and allows of thepassage of oil into the interior of the plunger. Vhen openings j areopposite the passage Z and the oil is allowed to escape thereto. In thismanner oil is forced past valve u and through pipe K to thesteamchest,whereit is distributed to the parts to be lubricated.

What I claim is- 1. In the lubricator described, the combina- IOO tion,with a spring-*depressed rod and means for operating it, of a hollowplunger connected to said rod,a valve situated within the plunger, andports or openings formed in saidpluuger and communicating through otherports with the parts to be lubricated, as described.

v2. In the lubricator described, the hollow plunger J provided withgroove i, openings j, and valve h, in combination with spring-de pressedrod E, and means for operating it, as described. v

3. In .the lubrieator described, the hollow plunger J, -provided withgroove i, openings j, and valve h, and communicating with ports l m forguiding the lubricant, in combination 4'with spring-depressed rod E, andmeans for operating it,` as described.

4. In the lubricator described, the Ycrosshead vD and 'bell-crank leverc, in combination with spring depressed rod E, and hollow 2o plunger J,the parts constructed, arranged, and operating as described and shown.

5. In the lubricator described, the crosshead D and bell-crank lever c,in combination with spring depressed rod E, and hollow plunger J, saidplunger provided with valve h, openings j, and groove z, andcommunicating with ports l m to guide the lubricant, as described.

In testimony whereof I aix my signature in 3o presence of two witnesses.

OMAR H. JEWELL.
